FASTENER.

Application led January 1G, 1926. Serial No.' V81,870.

This invention aims to provide an improved fastener easing.

Reference is made to a divisional application, Serial No. 93,905, filed March lith, 1926.

In the drawings, Which illustrate tivo preferred embodiments of my invention Figure l is a front elevation of the first preferred forni of casino;

Fig. 2 is a side elevation of the casing Shown in Fig. l;

Fig. 3 is a rear elevation of the casing sl'iou'n in Fig. l;

(i is a 'side elevation of the second preferred forni of casingg y Fig. 'i' is a rear elevation of the casing shovfn in Fig. 6; and

Fig. 8 is a cross-section showing the manner in which the second preferred form of casing is secured to its support.

Referng to the drawings and to that form of my invention illustrated in Figs. l through 4, l have shown a flush type easing comprising a fastener socket formed from a single piece of metal and fastening means formed integral with the casing for securing it to a support.

VEhe casing illustrated includes a .generally cylindrical body portion l having a reduced portion 2 toward its inner end, a iiange 3A at the outer end of the casing., a front face 4 generally dished toward a studreceiving aperture 5 and a rounded studengaging Wall 6 surrounding the stud-receiving aperture. The casing also presents, at its inner end, a plurality of attaching prongs 7 formed integral with the casing. In referring to the body portion l of the casing, I make reference to thatportion which is adapted to enter an opening in the support apart from the ange 3. This body portion is formed into two diameters, one being of a size to fit an opening in a support and the smaller portion 2 being provided so that the prongs may be bent outwardly initially for the purposes hereinafter described. These prongs, as illus trated in Figs. 2 and 3, extend from the edge of the reduced portion 2 and are initially bent outwardly from the casing so that the outer ends thereof are substantially in line with the face of the largest portion of the body portion l. The prongs are pref erably tapered toa point and arc wedge-- shaped thereby providing sharp pointed thin ends easily bendable.

The socket may be secured to the body 8 of an automobile, or other like support,

by first drilling a hole in the body 8 of the car, preferably in the wooden frame part, to provide a casing-receiving recess. it the bottom ofthe hole, l have provided an. annular anvii portion S, as iilustrated. in d. The socket fis then placed in the re'- cessI and the prongs i rest against the anvil portion so that, when pressure is applied to the flange P, the prongs will be forced outwardly by the anvil portion 8 and pierce the wall surrounding the recess.

rthe prongs being initially bont and easilyv bendable tm fd their ends, are therefore curved outwardly when forced into the Wood en part of the body 8, thereby hooking thorn selves into the body 8 to securethe socket thereto so that the ordinary outward strains exerted thereon., when a stud is locked in thc socket, 'will not pull the prongs if free from the wooden support. Any strain exerted upon the casing would be so remote from the prongs and so unevenly exerted thereupon that the prongs Would hold fast.

The forni of attacl'inient herein described and illustrated bythe drawing-js igs. `l through el.) may be equally useful in securing any casingpart of separable fastener to a- Wooden support, and is not necessarily limited to use in connection With the socket part of a separable fastener. The only portion of the socket Which extends beyond the side of the body 8 is, therefore, the flange 3, which, being of greater diameter than the body portion l of the socket, covers the edge of the socket-receiving recess and presents a neat and finished appearance.

Referring to the second form of casing illustrated in Figs. 5 through 8,1 have shown a fastener socket similar, in construction, to the one shown and described in the first form of socket. This vcasing is provided with a series of apertures l() (F ig. 6) spaced about the body portion l to provide a plurality of attaching elements 1l therebetween.. When securing this socket to the supports 8, I first place the casing into the aperture therein until the inner end thereof seats against the Wooden body portion 8 at the bottom of the recess. The flange 3 is spaced slightly away from the front face of the body S, but when pressure is applied thereto it is forced against the front face of the body, as illustrated in Fig. 8. During the above-mentioned operation, the metal of the casing between the apertures l() is distorted outwardly to form the attaching elements 11. The casing collapses between the apertures l0, and the attaching 'elements ll are forced into the wall of the recess to hold the socket casing in place, as shown in Fig. 8.

llVhile l have shown and described two preferred embodiments of my invention, it will be understood that l have done so merely vfor clarification and that niy in'venw tion is best delined in the following claims.

l claim:

l. A flush type casing elementi including 'a body part presenting at the inner end thereof a plurality of attaching prongs adapted to be bent outwardly from said casing to engage a rigid support when said casing is forced into a recess presented by the support and a flange at llie other en d adapted to seat against the outer face of the support.

2. A flush type socket (.-asing installation comprising, in combination, a rigid support presenting a recess therein having an anvil portion at the bottoni of said recess, a socket easing presenting at one end thereof a flanged portion and a stud-receiving aperture and at the other end a plurality of attaching prongs bent outwardly into the sup# port by said anvil portion to secure said easing to the support.

3. ln a fastener installation, a fastener element comprising a casing presenting means at one end thereof for engagement with a cooperating fastener element a flange at the same end and a plurality of attaching parts extending from said casing at the other end curvilinearly into a wooden support to secure said casing thereto.

Vfl. A fastener element comprising a casing presenting means at one end thereof for engagement with a cooperating fastener eloa plurality of initially bent attaching prongs extending outwardly from the end of the smaller of the two portions of said body portion and terminating in a plane parallel with the largest diameter of the'body portion thereby to permit said body portion to be forced into an aperture in a support of substantiall y the same diameter as the largest diameter ot said body portion, and a flange at the other end of the body portion.

7. A flush type socket comprising a onep'iece casing for application to a wooden supw port, said rasing presenting a vplurality of attaching portions adapted to be pressed into the support to secure said casing thereto and a flange at the outer end of said casing for limiting the inward movement of said cas- Y ing relative to said support.

ln testimony whereof, I have signed In name to this specification.
